I can't figure out what is causing this. Most of the time when I pause a BR rip it will freeze the system. The only way out of MC is to Ctrl+Alt+Delete into Task Manager then end the task.
What is weird is that I just updated W10 and my NVidea drivers and I could pause/play fine, for a while then it stopped working. Then I updated MC to the latest. Same behavior. I could pause/play for a while then it would freeze up when I paused.
EDIT: I did some more experimenting and it seems like it has to do with how long the video is playing. When I start a video I can pause/play as often as I like. After the video plays for apx 5 minutes pausing will freeze the system.
